ABSTRACT:
A document illuminator comprising a light-transmissive element having an embedded side emitting LED fitted in a cavity formed therein. The light-transmissive element is formed with one or more optical notches and is totally encased in a white surround to yield total internal reflection of the light rays emanating from the LED. The reflected light rays are collected at an aperture which in turn transmits high power and highly uniform illumination profile to illuminate a document.
